The need to keep $20k to $30k for maintenance is in line with our coach. We have the 1998 CC priced in the mid $100K range that was in pretty good condition. We have had our coach for 20 months, 10,000 miles and 154 nights on board. Our maintenance costs to date are roughly $25,000 and that does not include tires or batteries. I would bet that batteries show up next year or the year after. Other than chassis and engine work we are doing everything else ourselves.

Keep some money back and you should be fine.
